Effect types

GarageBand includes a variety of studio-quality effect plug-ins that you can use in your projects:

• Compressor: A compressor adjusts the volume of the patch to smooth out sudden level changes. Compressors can add punch and definition to a track or an entire song, and make it sound better when played on audio equipment with a narrow dynamic range.

• Delay: A delay effect repeats a sound like an echo. It can add a subtle sense of space to a sound, or create the impression that a voice or an instrument is in a large room, a cavern, or outer space.

• Distortion: Distortion effects, which include amp simulation and overdrive, change the tone of the original sound to re-create analog or digital distortion.

• EQ: EQ (short for equalization) is a powerful and versatile effect that lets you change the level of selected frequencies in a sound. You can use EQ to make both subtle and dramatic changes to your projects. EQ is likely the most commonly used effect in popular music. GarageBand patches have an EQ effect that lets you view and edit different frequency bands.

• Modulation: Modulation effects include chorus, flangers, and phasers. Like delay effects, they repeat the sound, but in addition, they shift or modulate when the repeated signal plays back. The signal can also be detuned relative to the original.

• Noise Gate: A noise gate reduces low-level noise by cutting off the sound when it falls below a certain minimum level. It is often used as the first in a series of effects, and is included on audio tracks to help reduce input noise.

• Reverb: Reverb simulates the natural reflections of a sound in a surrounding space. It can add definition and presence to voices and instruments, add ambience to a sound, or simulate different rooms and other acoustic environments.

• Others: GarageBand includes other types of effects, such as amp models, filters, pitch shifters, and other specialized effects.

Effects on the master track

The master track includes effects that shape the sound of the overall project. You can add, edit, reorder, and remove effects on the master track the same way as on other tracks. You view the effects on the master track by clicking the Master button in the Smart Controls menu bar, then clicking the Inspector button .

The master track includes Master Echo and Master Reverb effects. You can change the setting for the Master Echo and Master Reverb in the Effects tab when the master track is selected. Each audio and software instrument track includes a Master Echo and Master Reverb slider, which you use to control the amount of Master Echo and Master Reverb used on the track.
